YS-20
Yarn Speed and Length Meter

Combined hand-held tachometer:
– speed and length meter for filament and similar materials
– hand-held tachometer for contact and non-contact measurement e.g engine shafts

Tachometer with LCD display and 7 selectable measuring units

The most used yarn-speedmeter for circular knitting machines

Special Features

  • The yarn speed and length meter YS-20 combines the function of four separate instruments in one:
    – Speed and length meter
    – contact measuring of revolutions
    – contact measuring of velocity of rotation
    – non-contact measuring of revolutions
  • 2 Slide-in measuring adapters for yarn speed and length meter YS-20 make it simple to convert from contact to non-contact or to speed and length measurement
  • User-selected units
    Linear Speed: meters/min, feet/min, inches/min
    Length: meters, feet, inches
    Revolutions: rpm
  • The measurement is carried out, as long as the measuring key is pressed
  • Built-in memory for minimum, maximum and last values
  • Tachometer with big, easy to ready LCD display
  • Electricity saving electronic assures a long battery durability

Standard Features

  • Easy to use
  • Rugged plastic housing with rubber sheathing for firm and safe handling
  • Easy to read display
